Petrov was a leading graphic protagonist of the Yugoslav anti-war, anti-bourgeois and anti-nationalist Avant-Garde movement known as Zenitism, that flourished in the 1920s.

"The international review of new art and culture Zenit (1921-1926) enjoyed a reputation in the world as the only Yugoslav Avant-Garde journal, which was included in the international Avant-Garde scene at the beginning of the 1920s. Zenit was launched by Avant-Garde artist Ljubomir Micic in February 1921 in Zagreb."
